I finally bit the bullet and bought one of those converter boxes, since I rely on both rabbit ears, and an on-roof antenna that has actually been dangling by its cable off the side of the house for about a year. I've gotten used to fair-to-poor tv reception. Well I hooked that sucker up, let it search, it found about six digital channels already being broadcast, and they come in awesome. I've got the Superbowl on right now, and you would think that I had cable.

(added: and i'm just using some crappy rabbit ears to pick up the signal.)
